IMPROVEMENT IN SEED-PLANTERS.

Specification forming part of Letters Patent No. 2] 5.689, dated May 20,1879; application filed July 5, 1878.

To all whom it may concern:

Be it known that I, EMERSON O. STRANGE, of Taunton, State ofMassachusetts, have invented Improvements in Seed-Planters, of which thefollowing is a specification.

This invention relates to that class of seeding-machines in which areembodied a pilot or ground wheel and a seed receptacle or carrierprovided with suitable automaticallyactuated devices for effecting theescape of the seed from the carrier at the required periods and in thedesired quantities, such seeddropping devices being so connected withthe ground-wheel as to be actuated by the rotary motion thereof as itpasses over the ground; and the invention consists in certain devicesand the combinations thereof or therewith, as will be hereinafter morefully described and claimed.

Figure 1 is a side elevation of a seed-planter embodying my invention.Fig. 2 is a top or plan view of the same. Fig. 3 is a detached verticalsection of the seed-carrier, taken in the direction of line A B, Fig. 2.Fig. 4 is a detached enlarged view of the under side of the carrier, thevalve-lever, and valve-plate. Fig. 5 is an enlarged detached verticalsection as taken on line 0 D, Fig. 2.

In the drawings, a (I. represent the sides of the frame, united by thecross-bars c 0. d is the pilot or ground wheel, its axle t beingiournaled in sides a a. e e are the handles, united by hand-bar f. g isthe colter or drillopener, secured to frame a. h is the seedcoverer, andi the smoothing-roll, pivoted in arms j j. k is the seed-carrier, havingthe opening I in the upper portion thereof, and journaled upon the maleand female members an n of the arbor. o is a crank secured to member mof this arbor. p is a connecting-rod journaled upon wrist-pin b of cranko, and extending forward through the keeper or guide T, which is formedto admit a risingand-falling movement Without lateral variation.

s is a disk rigidly secured on axle t. In the outer face of this diskare secured a series of pins, a, which, as the pilot-wheel rolls overthe ground, are brought in contact with the shoulder '11 on rod 10,thereby imparting to it a forward and slightly-risin g motion. As eachpin passes this shoulder the coiled spring '60 draws back rod 19. Thusthe action of wheel 8, with its pins a and springs 10, tend to impart tocarrier 70 a swinging or vibrating movement. as is the valve-lever,pivoted to the under side of carrier k at y, as shown in Fig. 4. z isthe valve-plate centrally pivoted to lever 00, as shown, and havingarranged equidistant around its pivoted center a series of varying-sizedseed-passages, marked 1.

The valve-lever w is secured in place by the keeper 0, as shown in Fig.4. Spring d, secured to carrier 70, throws the lever as forward, asshown in Figs. 1 and 4.

When the carrier 7a is swung forward, by the means described, the freeend of lever 00 is brought in contact with the stop 0, and is therebyswung back in keeper 6, whereby the proper hole in plate z will bebrought in coincidence with passage a in the bottom of carrier is, andthe seed will pass through into the drill. 7

When pin a passes shoulder o the carrier swings back, and spring dthrows lever on forward, thereby causing plate 2 to close passage a inthe bottom of the carrier.

By adjusting plate 2 upon its pivot, so as to bring the proper sizedhole in coincidence I with passage a, any sized seeds may be planted.

Rod b is secured to the non-rotating memher a of the axis of the carrierk, and serves, by the swinging of the carrier, to stir the seeds thereinas they are carried past the rod, and so prevents their clogging passagea.

I do not claim a rotary seed-carrier; but

I do claim as my invention-- 1. The combination of vibrating carrier is,valve z, with its lever at, stop 0, and spring cl, all combined andarranged to operate substantially as described, and for the purposesspecified.

2. In a seeding-machine, the combination of vibrating carrier 75,vibrating lever .00, and valve-plate z, pivoted upon and vibrating withlever 00, and provided with a series of varions-sized seed-passages,arranged around the rigidly fixed in such non-rotative part, all

pivoted center, all substantially as described, substantially asdescribed, and for the purand for L116 purposes specified posesspecified.

3. In a seeding-machine, and in colnbina- I tion with the vibratingseed-carrier 70, the dii Witnesses:

Vided shaft 172 n, one part being rotative and EUGENE HUMPHREY,

the other part non-rotative and the rod 0, 1 '1. WV. PORTER.
